First check the neck bearing nut. torque to 40 lbs. If it is to loose you will get wobble.

Check your tire air pressures first.
18-20 psi rear and 36 psi front.
Your C-50 only weighs a little over 800 lbs.
Then take it for a ride.
In a C-50 some headshake is normal, usually below 20mph.
High speed shake (55-65mph) is usually wheel balance.
Since you have 2 wheels on the back, twice the odds one of them is out of balance.
Another suggestion to make it easier for you and others is to continue posting in the same thread you started originally so that all of the solutions and homework is in one place.
Do you really mean 26psi in the front?

Adjusted all tire pressure front to 26 psi rear to 19 psi. Also rechecked front stem adjustment found it to be to lose, in the neck, made that adjustment as well from 1/4 to 1 3/4. now it rides like a dream. Sweet and smooth !
Now try it at 36 psi in front and 18-20 in rear.

Tire pressure way to low! Do what Les says at minimum, then you won't have a chance of peeling a tire off the rim in a turn. I run 40 front and 22 back!

I agree, nothing worse than a rim cut tire
